Car headlights are an essential part of a vehicle’s safety features and they must be in good condition for drivers to see the road ahead clearly. To ensure that car headlights are functioning properly, manufacturers and technicians use a range of tests and measurements to evaluate their performance. In this article, we’ll look at the common tests used to evaluate car headlights, how to interpret test results, and how to improve the performance of your vehicle’s headlights.
Common Tests Used for Evaluating Headlights
A variety of tests are used when evaluating car headlights:
Light Output Test: This test measures the total light output from each headlight bulb in terms of lumens (a unit of brightness). It is usually carried out with a device called a lux meter which places the headlight bulbs at different distances from it to measure their total light output at each distance.
Efficiency Test: This test measures how efficiently each headlight bulb is converting electrical energy into light energy and is typically conducted using a power meter which measures current flow and voltage drop across the bulbs when they are switched on.
Aiming Test: The aiming test evaluates the alignment of each headlight bulb with the road surface. A technician will use a specific tool to measure the angle at which each bulb is pointing, and then adjust it if necessary.
Color and Intensity Measurement Test: This test assesses the color temperature of each headlight bulb, as well as its intensity. The technician will use a spectroradiometer to measure these properties to ensure that both bulbs are producing light at the same color temperature and intensity.
How to Interpret Results from Headlight Tests
Once all of the tests have been completed, the technician will analyze the results to determine if any adjustments need to be made. If a headlight bulb is producing light at a lower intensity or color temperature than its counterpart, then it may need to be adjusted or replaced. In addition, if one of the bulbs is not pointing at the correct angle, then it must be adjusted in order to ensure maximum visibility on the road. When it comes to replacing the headlights, Ford Excursion owners should look for the best replacement headlights, as they can significantly improve visibility and safety on the road.
How to Improve the Performance Of Your Vehicle’s Headlights
If you want to improve the performance of your vehicle’s headlights, there are several things you can do:
-
Replace any damaged or worn-out headlight bulbs with new ones that are brighter and more efficient -
Ensure that all headlight bulbs are aimed correctly by having a technician adjust them according to manufacturer guidelines
-
Clean and polish any lenses that may be foggy or discolored to maximize light output
-
Install additional lighting, such as fog lights or driving lights to supplement your vehicle’s headlights when needed
